在过去的2个小时里,我一直在网上寻找是否有其他人遇到此问题,而且看来还有很多问题,机器人没有任何答案对我有用.

The following From address failed: my@email.com

$mail->IsSMTP();
$mail->SMTPDebug = 2;
$mail->SMPTAuth = true;
$mail->SMTPSecure = 'tls';
$mail->Host = "smtp.gmail.com";
$mail->Mailer = "smtp";
$mail->Port = 587;
$mail->Username = "my@email.com";
$mail->Password = "password";

我已经为PHPMailer尝试了几乎所有设置,但无法弄清楚到底出了什么问题,我需要注意任何服务器设置吗？

我也尝试了普通的php mail()函数,但这也不发送邮件,尽管使用Drupal表单时它只是发送电子邮件.

解决方法:

首先,您必须配置正确的服务器以发送电子邮件(请参阅gmail.com)：

SMTP server address: smtp.gmail.com
SMTP user name: Your full Gmail address (e.g. example@gmail.com)
SMTP password: Your Gmail password
SMTP port: 465 or 587
SMTP TLS/SSL required: yes

在PHPMailer中：

$mail->SMTPAuth = true; // There was a syntax error here (SMPTAuth)
$mail->SMTPSecure = 'tls';
$mail->Host = "smtp.gmail.com";
$mail->Mailer = "smtp";
$mail->Port = 465;
$mail->Username = "YOU@gmail.com";
$mail->Password = "YOUR_GMAIL_password";
